• Optimize applications for performance, scalability, and security across the stack.
• Write clean, maintainable, and well-tested code (unit and integration).
• Participate in code reviews, sprint planning, and agile ceremonies.
• Troubleshoot and resolve issues across frontend, backend, and infrastructure.
• Follow best practices in version control, CI/CD, and deployment.

Qualifications
